I have a 1998 eclipse I was driving down the road and it shut off I tried to restart it and now all im getting is whining and it turns over really slow I took the alt starter and batt into advanced auto they all checked out ok I also tried to replace the coil pac and still the sa me I have spark but it seems like the engine is to slow to start I bought a haynes book but the problem isnt in there for troubleshooting can you point me in the right direction?
